No way it is going to fly. I just asked my brother who has his pilot's liscense and got the following response.
No, it could not take off and yes you are correct. An airplane is able to take off because of the pressure differential that exists between the top and bottom of the wing. Simply put, as speed increases pressure decreases. The air on the bottom half of the wing has a shorter distance to travel than the air on the top of the wing (since all wings have an airfoil shape to them). The lower pressure on the bottom of the wing wants to rise above the higher pressure on the top of the wing (i.e. lift). Since the plain would be on a treadmill only the wheels would be moving and not the actual aircraft. You could have a plane on a treadmill going 1000 mph and it would still never take off since it is the air moving around the wings that makes it fly, not the speed of the aircraft. That being said, the speed of a plane at takeoff does matter as it is generally a good measure, but not a defining measurement, of when a plane has sufficient lift to sustain flight.
Do you feel the wind in your face when you run on a treadmill the same as when you run on the street?
